W obrabiairikach pracujacych w cyklu aromaty¬ cznym badz sterowanych numerycznie niezbednie konieczne jest auitomatycizne zatrzymanie wrzecio¬ na roboczego w okreslonym polozeniu katowym, co warunkuje na przyklad automatyczna wymiane narzedzi lub wytaczanie bez ryjsy.In machine tools working in the aroma cycle necessary or numerically controlled automatic stopping of the spindle is necessary in the working position in a specific angular position, which determines, for example, automatic exchange tools or tool-free boring.

Znane sa rozwiazania ryglowania w po-s-taci tar¬ czy z gniazdem osadzonej na wirujacym elemencie, w które to gniazdo bezposrednio wsuwany jest ry¬ giel lub w postaci plaskiej krzywki o ksztalcie ser¬ cówki napedzanej dwoma hydraulicznymi tlokami, z których jeden napedza krzywke, a drugi wytra¬ ca urzadzenie z martwego polozenia.Locking solutions in the form of friction are known or with a socket mounted on a rotating element, in which the figure is directly inserted giel or in the form of a flat, ser-shaped cam a line powered by two hydraulic pistons, one of which drives the cam and the other wipes out the whole device from a dead position.

Istota urzadzenia wedlug wynalazku jest, ze po¬ siada zaopatrzony w amortyzatory hydrauliczny tlok polaczony z suwakiem zakonczonym rolka o- sadzonym suwliwie w kostce wyposazonej w mi- krolaczniiki i prowadnice dla wodzika zaopatrzone¬ go w zderzaki i zwiazanego z suwakiem za po¬ moca sworznia, krzywke z przeciwwaga osadzo¬ na na walku polaczonym przekladnia zebata z wrzecionem obrabiarki oraz czujnik indukcyjny osadzony w oibtsadzie.The essence of the device according to the invention is that sits down equipped with hydraulic shock absorbers piston connected with a finished slider, roller o- planted slickly in a cube equipped with rebels and slider guides provided it in the bumpers and tied to the zipper for the half by the bolt, the cam with the counterweight is mounted on the coupled shaft gear with machine tool spindle and inductive sensor embedded in the oibtsad.

(Przedmiot wynalazku jest przedstawi-cny w przy¬ kladzie wykonania na rysunku, na którym fig. 1 Jest przekrojem wzdluznym urzadzenia, fig. 2 — przekrojem wedlug A-A na fig. 1 i fig. 3 — prze¬ krojem wedlug B-B na fig. 1.(The subject matter of the invention is illustrated in, for example, the embodiment in the drawing in which fig. 1 Is a longitudinal section of the device, fig. 2 - the section according to A-A in FIG. 1 and FIG. 3 is shown in FIG typeface according to B-B in fig. 1.

Urzadzenie pozycjonujace wedlug wynalazku sklada sie z tloka 1, który jest wyposazony w a- mortyzaitory 2 i 3 powodujace lagodne dochodze¬ nie tloka 1 do skrajnych polozen oraz jest pola¬ czony z suwakiem 4 zakonczonym rolka 5. Su¬ wak 4 jesit osadzony suwliwie w kostce 6, która posiada prowadnice do osadzenia w nich wodzika 7 zaopatrzonego w zderzaki 8 i polaczonego z su¬ wakiem 4 za pomoca sworznia 9. Kostka 6 jest ponadto wyposazona w dwa mikrolaczniki 10. iRolfka 5 wspólpracuje z krzywka 11 osadzona na walku 12 polaczonym przekladnia zebata z wrze¬ cionem 13 obrabiairki. Krzywka 11 moze równiez byc osadzona bezposrednio na koncówce wrzecio¬ na 13. Celem wywazenia krzywka 11 jest zaopa¬ trzona w przeciwwage 14. Krzywka 11 jest cylin¬ dryczna i tak wykonana, ze posiada na obwodzie jeden punkt najwyzszy, od którego w obu kierun¬ kach zarys krzywki opada tworzac w koncowej fazie wglebienie wykorzystane jako gniazdo regu¬ lujjace. W czasie pracy wrzeciona 13 rolka 5 wraz z suwakiem 4 jest wycofana w górne polozenie, tak, ze krzywika 11 wirujac nie koliduje z rol¬ ka 5.Positioning device according to the invention consists of piston 1, which is equipped with a- mortyzitors 2 and 3 causing mild investigation not the piston 1 to the extreme positions and there is a field connected with slide 4 finished roll 5. Su¬ the hole 4 is mounted snugly in the cube 6, which has guides to embed the slider in them 7 provided with bumpers 8 and connected to the suction plug 4 with pin 9. Cube 6 is Moreover, it is equipped with two micro switches 10. iRolfka 5 works with cam 11 mounted on shaft 12 combined with a gear with a gearbox 13 machine tools. Cam 11 can also be seated directly on the tip of the spindle on 13. The purpose of the balancing cam 11 is the supply the shaft is counterweighted 14. Cam 11 is cylindrical drastic and made so that it has the circumference one highest point from which to both At the end, the cam profile descends to form at the end the cavity phase used as the regulating seat lujjace. During the work of the spindle 13, roll 5 together with the slide 4 it is retracted to the upper position, so that the rotating curve 11 does not interfere with the roll ka 5.

Pozycjonowanie wrzeciona 13 odbywa sie po wy¬ laczeniu napedu i calkowitym, wyhamowaniu obro- 1002023 100202 4The positioning of the spindle 13 takes place after the trigger connection of the drive and complete braking 1002023 100202 4

Claims

Patent claims

1. A control device for adjusting rotating elements, in particular spindles of machine tools, to a certain angular position, characterized by the fact that it has a hydraulic piston (1) connected to the slide (1) with shock absorbers (2) and (3). 4) a finished roller (5) mounted securely in the cube (6) equipped with micro-links (10) and guides for the slider (7), provided with bumpers (8) and connected to the slide (4) with a pin (9), a cam (11) with counterweight (14) mounted on a shaft (12) connected with a gear gear with a spindle (13) of the machine tool and an inductive sensor (16) embedded in the holder (15).

2. Device according to claim A method as claimed in claim 1, characterized in that the cam (11) is cylindrical and shaped in such a way that it has one highest point on its circumference than the icitirre in both directions, the outline of the cam descends to form a hollow serving as a locking seat at the end. Fig. I. T6w. The hydraulic piston 1 moves the slider 4 and the roller 5 by pressing on the cam 11 causes the rotation of the roller 12 until the roller 5 is at the lowest point of the cam 11 which corresponds to stopping its rotation at a strictly defined 5 angle position. The cam 11, due to the gear ratio of the gears 1: 1, has the rotation equal to the spindle 1

3. The positioning of the cam 11 is equivalent to the positioning of the spindle 13. In order to avoid the stop of the cam 11 at the so-called "dead point", an inductive sensor 16 is mounted in the holder 15, which causes the spindle 13 to turn on temporarily to to move it to a different angular position. The inductive sensor 16 is only energized when the spindle 13-stops in the unfavorable position. - 20 kami 8. >> 100202 no. 2. Fig. 3.
